out of curiosity, is it even possible to make glass or any solid object that's 100% transparant with a refractive index of 1.0?I mean, how would you even see it or know your holding it? I guess it's the equivalent to air being blown towards you. But even if you freeze air to solid matter, you see it.

air's refractive index depends on its density which depends on stuff like wind or temperature. If you could match the ior of the object and environment with bot being equally refractive it would'nt be invisible but just indistinguishable from its surroundings. In fact this has been done with water and the right kind of plastic, drop both in a jar and the plastic seemingly disappears.

Wow. That's amazing! I read online that they have these things called Metamaterials which contain a negative refractive index which essentially shift an object completely in the opposite direction. So if you were to look at a lake with a negative refractive index, you would see the scuba diver swimming in the air above the lake. It makes you virtually invisible, at least in terms of your percieved coordinates.

I rob a bank, get caught and give the police a false name. To the best of my knowledge, after the age of 8 there is not a single picture of me in the possession of the government or anywhere really, never been printed, never been dna sequenced. There is no solid proof i even exist. So basically i tell them a false name and that i live alone in the forest and that i lost my birth certificate, what would they do? Convict me under the false name? And then when i make my escape, who would they look for? What if i just grow a beard and return to my life? Even if i lived across the street from the prison my alias is supposed to be in they would never even have a clue!

what if

I travelled back in time 100 years but also displaced myself 100 lightyears away - then it would be impossible for me to affect my former self thus avoiding the time paradox. Obviously it would be a problem if i travelled right back these 100 lightyears and landed 200 years before i set off.

To avoid that there can only be a single point in space where you can travel back in time. Moving to the other side of the equation there must also be a single point in time where space can move backwards(inverse on itself) Curiously enough the big bang matches this description perfectly for the position of its origin is the center of the universe and its also the position in time where space came into existence out of ???

This leaves the question - what did the space invert itself out of? couldnt have been another universe since that universe already used up its unique point in time and space so must have been a black hole or a white hole or something we cant even imagine. Obviously all of this means that pop music must die.
